SPOKE- EXTRACTO R.

SPECIFICATION forming part of Letters Patent No. 319,512, dated June 9, 1885.

Application filed March 19, 1885.

To all whom it may concern.-

Be it known that I, GUSTAV A. SonoENIKu, a citizen of the United States, residing at Lebanon, in the county of Dodge and State of Wisconsin, have invented a certain new and useful Device for Pulling Spokes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention-to be hereinafter claimed-- is of a device for pulling spokes out of ahub.

In the accompanying drawings, Figure 1 is a perspective view of my device with a hub and spoke in dotted lines, the whole be-.

ing in position for pulling ,the spoke. Fig. 2 is a side View of the spoke gripping and pulling mechanism. Fig. 3 is a vertical sec tion of the spoke-gripping mechanism. Fig. 4 is a horizontal section of the spokegripping mechanism on the line as m of Fig. 3. I

The same letters refer to like parts in all the views.

The rigid longitudinal frame a is provided with a rod, 1), extending lengthwise of the frame, and passing through its front and rear ends in apertures therefor. Near its front end this rod 1) is provided with an external screw-thread corresponding with and fitting into a thread on the inside of the aperture, through which said rod passes in the front end of said frame a. This rod fits movably into the aperture through which it passes in the rear end of the frame a. On its front end this rod 2) carries a swivel block or cushion, c, in which it freely revolves. At its rear end it has abell-crank handle, (I, through which to apply power to cause it to rotate.

The frame 6, having rigid ends and par allel sides is provided with avertically-sliding cross-head, f, supported upon the lower end of vertical rod g, the said end of which rod has a free rotary or swivel movement in said cross-head. This crosshead has in its two horizontal ends recesses for the reception of the parallel sides of frame e, upon which No model.)

sides said cross head has a free vertical movement.

The rod 9 is provided with an external screwthread turninginacorrespondingscrewthread in an aperture, through which it passes in the rigid top end of frame 6 at h. The rod 9 is also provided with a bell-crank han dle, z, for rotating it. This frame eois suspended upon the frame a, near its front end, by two rods or levers, j j, one on each side, pivoted at one end to the frame a, centrally pivoted to the frame 6 near its lower end, and at their upper ends being pivoted to the respective ends of the resisting-arm 7c.

The arms j j are about as long as an ordinary hub, but the necessary adjustments of this device to hubs varying in size are secured by the form and pivotal connections of the several parts of the device.

The n-shaped guard at, pivoted at its re spective ends to the frame a is for restraining and controlling the free end of the spoke, if by accident or otherwise it is not held rigid by the gripping device before described.

I preferably provide slight recesses in the upper side of the lower end of the frame 0, and in the lower side of the cross-head f, as shown at an, for the reception and better holding of the spoke.

To use this device, the hub is placed vertically in front of the device, and the spoke to be pulled out is thrust through frame 6, below the cross-head f, the hub being brought firmly up against the cushion c and arm is, and the spoke is gripped firmly between the lower end of frame 0 and cross-head f by turning down the rod 9, whereupon, by rotating the rod 1) against the h ub, the hub is pushed off of the spoke.

What I claim as new,and desire to secure by Letters Patent, is-

1. The spoke-pulling device consisting of the frame a, the screw threaded rod 1), rotating in frame a, the frame 0, suspended upon frame a, the cross-head f, sliding within frame 0 and carried upon and moved by the screw-threaded rod rotating in frame 0,-in connection with such frame clamping the spoke, and the resisting-arm 70, independent of frame a, substantially as described.
